[PATCH 00/11] audio: more improvements

[Volker Rümelin]

A few patches from my audio patch queue.

Patches 1 - 2:
If a guest selects an unsupported sample rate, an error message is 
currently shown. The first patch takes care to suppress the error 
message and reports with the qemu_log_mask(LOG_UNIMP, ...) function that 
this is not supported. The second patch is needed because there are two 
code paths to reach the qemu_log_mask() function in the 
audio_pcm_sw_alloc_resources_* functions. The second path prints an 
additional error message up to now.

Patches 3 - 4:
General improvements.

Patches 5 - 9:
These patches remove the audio_calloc() function. The GLib g_new0 macro 
is a better replacement for audio_calloc() and we have one less 
audio_bug() function call site. There's one exception where g_malloc0() 
fits better.

Patches 10 - 11:
Audio playback and recording with the ALSA audio backend currently 
doesn't work well with the default audio settings.

  audio: log unimplemented audio device sample rates
  audio: don't show unnecessary error messages
